I am a newbie and just purchased the black box bundle and would like to know how to set up the parameters of my machine in the software.. my machine is a China 6090 cnc router
download and install OpenbuildsCONTROL . in CONTROL click 'GRBL Settings' select whichever Openbuilds machine most closely resembles your machine in configuration (belts or screws) and size. make sure homing is turned off even if you have homing switches click 'save to firmware' press the reset button on the blackbox set a small jog step and make sure the tool jogs in the correct directions pre-calibrate : use what you know about the machine to preset the steps/mm settings, maybe use a calculator to help you. Calibrate, you can use the wizard in CONTROL or follow the instructions. (which is a bit more accurate since you can measure over a longer distance). At this point you have directions correct and step/mm calibrated... now, if you have home switches, you can use the troubleshooting tab to check that they work correctly then enable homing and check directions by resetting grbl and homing (finger on Estop!) to check that homing goes in the correct directions. if you do not have home switches, then learn to fake the home so that everything works the way Gcode expects it to. now, cut a simple test in some insulation foam.
do you have pictures of your wiring on the blackbox? i got a china 6090 myself and want to convert to the black box motion controll but stuck on the spindle wiring
The calibration is done the same way for gear rack. You calibrate steps/mm using the wizad. However, when you design your items and generate the gcode using your CAM software you can use inches. You can also chose "Inch Mode" in OpenBuilds control.
